Well, of course pull ups and dips work your shoulders, as do regular push ups…although not quite like handstand push ups of course. You can always get a heavy dumbbell or something like that and do standing overhead presses!
Hmm yeah it handles the stability portion of those exercises. I guess I’ll start with one arm push up top position hold then do it elevated, then progress to one arm elbow planks and then do that elevated.
Weights aren’t an option for me, the nearest gym is quite far away.
Well, if you have a strong low ceiling, you can press your hands against it like a handstand push up and counter with the resistance of your legs. To make it a bit easier to gauge, pick one foot up and just use the other.
